, Thisinvention relates to improvements in that type'of apparatus usually referred to as gas-savers. 1 i

its

n is the object'of this invention to mduce a device of a simple construction that can bereadily applied to the intake mani fold of an internal combustion engine and I by means of which the interior of the manifold can be connected witli'theinterior of the crankcase ofthe engine, for the purpose of sucking gas andvapors from the crank case 'andinixing the same with the fuePm'iR- ture-thatfpasses from the carburetor to they engine cylinders.

1 pass bythe piston and into the crankcase During the operation of an internal combustion engine, a considerable amount of the gasoline or liquid fuel,*which is vaporized and transferred tov the engine cylinders, will during'i 'the operation of the engine. The

hydrocarbon gases thatescape from the com 'bustion chamber ofthe cylinders to'the crank case represent a-considerableloss and besides the newfuel mixture and, in this manner the thisthese vapors, after they reach the crank case condense and the. "gasoline becomes mixed with the lubricating .oils and destroys its lubricating properties.-

, It is evidentthatif" he vapors that es-j cape from the cylinders into the crank case canbetreturned to the intake manifold they will-again enter the cylinders together with energy which they contain will finally be transformed intouseful work; It is also evidentthat if these gases or vapors are removed .fr mFtheicr ank case as fast as they. enter,

3 thatfthe're will' b e no opportunity for, them to condense and therefore the gasoline which 1 they contain will not have an opportunity to become mixed with thelubricating oil.

' This invention, briefly described, consists of an elongated tube, whose sides are pro-E videdwith a plurality of'perforations spaced alongthe' f length of the tube and within which is located a plunger that can be reciprocat'e dso asto cover or uncover these opening's. 'A tubular member surrounds that pertion of "the" tube. which contains 7 the opening'sfandhas a larger innerdiameter than theouter diameter of the tube so as to'provide an annular cylindrical chamber between the outer surface of the tube and the inner surface of the tubular member. The ends of the tubular member are connected with the outer surface of the tube so as to close the 4 ing kerosene or other liquid into the engine cylinders for the purpose of removing carbon and for the purpose of priming the engine in caseit is found difficult to start the same during cold Weather,

" Having thus briefly described the invention, the same will now be described in detail andifor this purpose reference will be had to the accompanying drawing in which the preferred embodiment thereof has been illustrated and in which:

" Fig. 1 is a side elevation of an internal combustion engine showing my gas saver in place'thereon;

- Fig. 2 is a fragmentary view showing the gas saver connectedin the line from the intake manifold to the vacuum tank;

' Fig. 3 is a longitudinal sectionthrough my improved gas saver and Fig. 4 is a section taken on line 44, Fig.3, parts being broken away to better show the construction.

In the drawing numeral 1 represents an internal combustion engine provided with a crankcase 2 having a breather pipe 3 in connection therewith. Numeral-4 represents the intake manifold, 5 the exhaust manifold, and 6 the carburetor, while numeral 7 represents a vacuum tank of the ordinary construction,

My improved gas saver consists of a tube 8 which is provided with a plurality of openings 9 spaced longitudinally thereof. A plunger 10 is slidable in the inside of the tube and serves to cover the openings 9 and to uncover thesame. This plunger is of such length'that when it is in its innerm'ostposition, all-of the openings'9- will be closed. One

, end of tube is provided with a threaded por- I ings 9. The inside diameter of tubular memcally'located bosses 16 and 1? which havethreaded openings. The opening in boss 17 ber 12 is greater than the outside diameter of tubes-8 and there-forea n annularchamber-- 15 is provided which 1s in communication .With't-he inside'of tube 8 through. openings 9. Member 12 is provided with diametrihas connected therewith a lcoupling. 18-that issecured to one end of the tube 19.Tl1e otherend; of this tube is incommunication -with-the interior of the crank case through the breathe-r pipe 3. =The'r'eason why tube 19 is-connected with the breather pipe instead of directlywith the crank case isthat if it wereconnecteddirectly with the crank case a lot of; oilspray would be carried away operationand that the plungerlO is moved mixed with the vapors andthis would be objectionable, Where-as, by being. connected with the' breather pipe, very little, if 'oi l,-Will be carried away-when the device is'. in operation. Connected with the opening-in boss 16 is a valve member comprising two parts 19- and 20. The part- 19 is madein the form-of'an L, Wl1il(5 part 20 is made-in the shape of a funnel, The outerend ofmem her 1 9' has, a threaded opening 21 which t'er-y minates in a smaller opening 22. Memben .20 has a threaded portion23 that cooper-' ates with the threaded surfaceot opening 211 and terminatesin a conicalend 24 that; coop-- erates with the valve seat to close-the opening; An opening 25 extends from the bOlltO l'IlyOf the recess 26 to the outside of member 24. By turning member 20, the interior; of-thecup or recessr26can be'put in communication r e I N prising. an v en'longated tube hav-lng a pluraln,

with theannular' chamber 15.. A- wire 27 is connected with I the outer end otfthe plunger lO and is held in placewby. means; of a set screw 18; This wire passes through altube 29 and'is connected with ahandle 30stha'tis carried by the instrument board 31.-' hen vacuum line',bylmeans'ofa Tin the manner;

shownin Fig. 2.

I Let us now assume that the 1 engine isinr so as to uncover a plurality of the openings 9.1 The interior of chamber 15" willnow be" placed in communication with. the interior.

of the manifold and as'the' pressure themanifold is less than atmospheric, gas and vapor will flow from the crank casethrough tube l9 into chamber 15 and thence through the openings 9 into the manifold. This acgaseousisvapors and returngthem'to the env gine, thereby preventing the condensation of gasoline within the crank case. L I
